In Killer Apes, Naked Apes, and Just Plain Nasty People, anthropologist Richard J. Perry delivers a scathing critique of determinism. Exploring the historical context and enduring popularity of the movement over the past century and a half, he debunks the facile and the reductionist thinking of so many popularizers of biological determinism while considering why biological explanations have resonated in ways that serve to justify deeply conservative points of view.
